Mount PSU upside down?

I have a Corsair CX600m. The 24 pin connector (and the cpu power connector for that matter) come out of the wrong side of the psu. I looked at it after I installed it and just thought... "Wtf. How is that a good idea" and it kind of messed up my case. To combat this I've mounted the PSU upside down, as the screws fit either way. Except it's on the bottom of my case. Is that okay? Will it overheat?

If anything, the inside of my computer is a few degrees cooler, I'm guessing because my PSU isn't sucking the cold air out of the bottom of the case. Well, that's my theory.

But is it good for the PSU itself? It has a big dust cover and grill on the bottom of my case - kind of looks like it was supposed to be upside down. Also, the writing on the side is right-way-up. (All though I guess it would have to be, for if it was mounted at the top of a case). And it's not like there's no space, the case has feet that suspend it from the floor a little.

I also done this because I am a sucker for dropping screws and things when I'm messing about in the computer, I haven't actually dropped anything inside the PSU before but I have come close, and I wouldn't want that to happen. (Screws have dinged off of the fan rail a few times.)

In most configurations... that is right side up. What is your case? I can almost assure that you had it upside down to begin with. You want the PSU sucking from the bottom vent because it isolates the system making it so it does not heat the air on the case and prolongs all of the parts in your computer.

Yes it should be just fine, mind you this is the old way to mount a PSU to the case (upside down)

Just be careful with your mobo though, the Corsair CX series 24 pin latch is poorly designed making it incredibly difficult for the 24 pin cable to "snap" into place to the 24 pin socket. Don't put too much pressure on your mobo!

If you have ventilation grill on the bottom of your case fan should face down.

My computer was originally made by Cyberpower. It wasn't very good. Cable management was poor, the PSU was even poorer (fan would become lose and computer would start sounding like pots and pans banging together, and the fan would stop intermittently. Considered RMA, but I wanted a decent PSU) and I've basically had to upgrade everything except the Mobo. Not a bad PC now, good for what I use it for anyway.

I agree with what you are saying - the 24 pin is extremely awkward to snap into place, but I have worked out a way to do it efficiently, all though it is very hard to take off and I'm afraid at some point, it might snap. But so far so good. I ease it in, from side to side, then bend the clip over when it's pushed in all the way.

The original PSU that came with my computer was ubranded until I took it out and saw some generic brand I'd never heard before on the reverse (Red something I believe) - so you are probably right, it was probably meant to be the other way around, but this is how they installed it, so I figured it was the norm.

I have a Cooler Master Elite 430 USB 3.0- again, not a fantastic case, I didn't pick it, but it looks nice, and thank god I have decent cable management. Not a single routing hole (but I have considered modding - I saw a guy on youtube cut a hole in the side panel, insert grommets, and screw a black baking tray to the side, worked amazing for the cables).

I find the idea of modding fun, so I'm not going to look for a new case as of just yet. But the case has a bottom grille with a dust cover, so I guess it will be fine. I just assumed that because heat rises, the PSU may get too hot with the fan being on the underside.

You know, I'm kind of thankful that the PC had a few problems because I knew nothing about PC's when I bought it. But I hate paying for somebody to repair my PC, it means I have to be without it for x amount of time, so I just started fixing things myself. I've learnt so much in the past couple of weeks and rewired it multiple times and installed multiple new components. Great way to start something that has now become a hobby.
